LOOM.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed March 13, 1906. Serial No. 305,829.

To all whom it may concern:

Be it known that I, Mosns PERREAULT, a citizen of the United States,residing at New Bedford, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inLooms, of which the following is a specification.

The object of my invention is to prevent the imperfectio'ns in cloth,which are caused when the filling breaks, by the succeeding thread notoccupying the position it should, and thereby causes what is called, athin place, in the cloth. As each filling thread is placed in the warp,or, in other words, every time the loom makes a pick, the warp is fedalong a certain distance according to the number of picks per inch thecloth being woven, is to have. Now when the filling breaks, or runs out,and the loom is stopped through the agency of the filling fork, it doesnot stop instantly, but makes a portion of, if not a whole revolution,and perhaps more, through the action of the operative in piecing up thebroken thread, or supplying the shuttle with filling. The purpose ofthis invention, through the ordinary action of the filling fork, is toarrest the motion of the warp at the instant the filling fails, andcause it to remain stationary, until the loom is put in motion again bythe shifting lever. This object and purpose, I attain by the mechanismillustrated in the accompanying drawing, in which Figure 1 represents aportion of that end of a loom which is provided with the warp movingmechanism, or cloth take up, and showing my improvement attached to theloom. Fig. 2 is an enlarged view of a part of my invention, so as toshow more clearly its construction and operation.

Similar letters refer to similar parts in the several views.

The letter a, represents the ordinary ratchet wheel, actuated by thereciprocating ratchet b, which is given its reciprocating motion, by aneccentric inclosed within the box d, fixed to the cam-shaft c, of theloom, all in the usual manner, and which constitutes the mechanism whichmoves the warp and winds the cloth on the cloth roll.

In Fig. 2, which is a side view of a portion of the cam-shaft of a loom,the eccentric which gives motion to the ratchet b, is made to turnloosely on the shaft 0, and is provided with the clutch q, which isadapted to engage with a similar clutch r, secured to the shaft 0. Onthe opposite side of the eccentric and its inclosing box d, and pressingagainst it, is mounted the spiral springs, which is kept in place, andits tension regulated by the nut 15. The rod 0, is rigidly secured tothe lever h, at u, and is provided with the wedge shaped end p, which isadapted to disengage the clutch q, from the clutch 1", when forcedbetween their inclined edges. The lever h, is pivoted to the stud i, andis flexibly connected with the arm 9, at k, and l, by the rod m.

The letter e, represents the usual rod which extends across the loom,and which has a partial rotation in the direction of the arrow, when thefilling fork operates the mechanism to shift the driving belt of theloom to the loose pulley, and stop the loom. When this action occurs,the wedge shaped end of the rod 0, is forced between the inclined edgesof the clutches r, and q, and disengages them, and thereby instantlyarrests the motion of the mechanism which moves the warp in thedirection of the cloth roll. When the sh ifting lever is moved to startthe loom, the rod 0, rotates in the opposite direction, which motion,through the arm 9, rod m, lever h, and rod 0, causes its wedge shapedend 1), to be withdrawn from between the clutches q,

and r, and the spring 8,, then operates to force the clutch q, intoengagement with the clutch r, which action instantly sets the warpmoving mechanism in motion, It will be observed, that when the clutchesq, and r, are disengaged, the loom may be revolved, or turned over anynumber of times without disturbing the position which the warp occupiedwhen the filling fork operated to stop the 160111.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is

1. In a loom, a take-up mechanism, a cam shaft pro vided with aneccentric having a clutch face, another clutch face fixed upon theshaft, means for holding the clutch faces normally together, arrckshaft, a lever having connection with the rock shaft, and a r.:d havingcoir nection with said lever and provided at one end with an enlargementfor engagement between the clutch faces to separate them to arrest thetake-up mechanismv 2. In a loom, a take-up mechanism, a cam shaft provided with an eccentric having a clutch face, another clutch face fixedupon the shaft, means for holding the clutch faces normally together,and means having connection with the take-up mechanism and provided withmeans normally free of the clutch faces and for engagement hetween themto separate them and automatically arrest the take-up mechanism.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
